CompTIA 220-1201 Online Questions & Answers

• Question 471:

  A technician recently replaced a user ' s laptop screen. Since then, the user has had trouble connecting to wireless networks.

  Which of the following should the technician do?

  A. Verify that wireless technologies are compatible with the updated hardware.
  B. Reinstall the wireless drivers after the OS is reloaded.
  C. Reconnect the antenna to the system board.
  D. Reset the network services.
  C. Reconnect the antenna to the system board.

  ---

  Explanation

  When a laptop screen is replaced, the technician typically removes the display bezel and may disconnect cables routed through the hinge area. The Wi-Fi antennas in most laptops are mounted inside the display assembly (often along the top edges of the screen) and their thin coax antenna leads run through the hinges to the wireless adapter connection points on the system board or directly onto the Wi-Fi card (MAIN/AUX terminals). If one or both antenna leads are left unplugged, pinched, or poorly seated during reassembly, the laptop will still detect the Wi-Fi adapter, but wireless performance will be severely degraded-weak signal strength, intermittent connections, inability to see networks reliably, or frequent dropouts. This symptom appearing immediately after a screen replacement strongly indicates a physical antenna connection issue rather than a driver or software problem. Reinstalling drivers or resetting services would be more appropriate after OS changes or configuration corruption, not after display hardware work. Compatibility of wireless technologies is unrelated to swapping a screen. Therefore, the best CompTIA A+ troubleshooting step is to open the unit and reconnect/secure the Wi-Fi antenna leads to the system board /wireless card.

• Question 472:

  A management team is concerned about enterprise devices that do not have any controls in place.

  Which of the following should an administrator implement to address this concern?

  A. MDM
  B. MFA
  C. vpn
  D. SSL
  A. MDM

  ---

  Explanation

  Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.

  Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.

  Why Not C (VPN): VPN secures communication but does not enforce device controls.

  Why Not D (SSL): SSL secures data in transit but does not provide device management.

• Question 473:

  A business purchases a computer with a built-in WWAN card.

  Which of the following technologies does the computer's WWAN card support?

  A. SIM
  B. NFC
  C. Bluetooth
  D. Wi-Fi
  A. SIM

  ---

  Explanation

  A WWAN card provides cellular wide-area network connectivity (such as LTE or 5G) for a laptop, allowing it to access mobile data networks similar to a smartphone. To authenticate to a cellular carrier and identify the subscriber account, WWAN devices typically use a SIM (Subscriber Identity Module) or an embedded SIM. The SIM contains carrier subscription information and security credentials used during registration on the cellular network. Without a valid SIM or eSIM profile, the WWAN radio may be present, but it cannot complete carrier authentication and will not provide cellular data service.

  The other options are different wireless technologies that are not the defining requirement for WWAN service. Wi-Fi is WLAN connectivity, usually provided by a separate Wi-Fi adapter. Bluetooth is a short-range personal area networking technology for peripherals and tethering. NFC is very short-range communication used mainly for tap-to-pair or payments. Therefore, the technology a built-in WWAN card supports in this context is SIM.

• Question 474:

  Which of the following is commonly affected by high latency?

  A. Satellite
  B. Fiber
  C. Cable
  D. DSL
  A. Satellite

  ---

  Explanation

  CompTIA A+ emphasizes that satellite internet connections inherently suffer from extremely high latency because the data must travel from the user's antenna to satellites orbiting tens of thousands of miles above Earth and back. Although satellite systems offer broad geographic coverage, this long travel distance introduces noticeable delays often 500ms or more.

  Fiber, cable, and DSL operate through terrestrial wiring and have far lower latency due to short signal paths. Fiber, in particular, is the fastest and lowest-latency connection type.

  Satellite delay significantly impacts VoIP calls, video conferencing, online gaming, and real-time applications. The A+ exam specifically notes latency as a major performance characteristic of satellite service, distinguishing it from other broadband technologies.

• Question 475:

  A user needs cellular internet connectivity for their laptop without using an external device.

  Which of the following technologies can the user use on their laptop to achieve this connection?

  A. Bluetooth
  B. Hotspot
  C. SIM card
  D. NFC
  C. SIM card

  ---

  Explanation

  A SIM card enables a laptop to connect directly to a cellular network when the laptop includes an integrated mobile broadband (cellular) modem (often referred to as LTE/5G capable). In this setup, the SIM provides subscriber identity and authentication details required by the carrier, allowing the laptop to register on the cellular network and access mobile data without relying on separate tethering devices. This aligns with CompTIA A+ Core 1 coverage of mobile and wireless connectivity options, including cellular data capabilities and the components required to use them.

• Question 476:

  Which cloud model provides hardware, storage, networking, and virtualization but requires customers to manage the OS and applications?

  A. SaaS
  B. PaaS
  C. IaaS
  D. XaaS
  C. IaaS

  ---

  Explanation

  Infrastructure as a Service (IaaS) provides the foundational computing components: virtualized hardware, storage, networking, and hypervisor resources. CompTIA A+ explains that customers using IaaS are responsible for installing and maintaining:

  The operating system

  Applications

  Patches, updates, and configurations

  This model gives organizations maximum flexibility because they can build custom server environments without purchasing physical hardware.

  In contrast:

  SaaS (A) provides fully managed applications--users do not manage OS or software.

  PaaS (B) provides a development platform and tools but does not allow OS management.

  XaaS (D) is a broad term meaning "anything as a service," not a specific model.

  Thus, IaaS is the only model where OS-level control remains with the customer.

• Question 477:

  An office manager must scan a 300-page contract quickly. They are worried about scanning each page one at a time.

  Which feature will speed up the process?

  A. Flatbed scanner Duplexing
  B. Automatic document feeder
  C. Orientation configuration
  C. Orientation configuration

  ---

  Explanation

  CompTIA A+ details that an Automatic Document Feeder (ADF) allows multi-page documents to be scanned automatically without manually placing each sheet on the flatbed. This drastically increases scanning efficiency for large documents.

  Flatbed scanners require manual placement for every page. Duplexing scans both sides of a page but does not feed multiple sheets by itself. Orientation configuration only affects image alignment.

  The ADF is explicitly highlighted in the A+ study guide as the primary feature used in business environments when scanning high-volume documents efficiently.

  Thus, the ADF is the correct solution because it automates page feeding and dramatically reduces scanning time, especially for hundreds of pages.

• Question 478:

  A technician must install additional RAM in a desktop computer.

  Which of the following types of RAM will the technician most likely use?

  A. Static
  B. ECC
  C. DIMM
  D. Registered
  C. DIMM

  ---

  Explanation

  Desktop computers most commonly use DIMM modules (Dual Inline Memory Module) for system memory. DIMMs are the standard full-size RAM sticks installed in desktop motherboard memory slots and are available in modern DDR generations such as DDR4 and DDR5. CompTIA A+ Core 1 expects you to distinguish common form factors: desktops use DIMM, while laptops typically use SO-DIMM (Small Outline DIMM).

  The other options are either specialized memory types or not the typical "type" used to describe desktop installation. Static refers to SRAM (static RAM), which is used for CPU cache and other internal high-speed buffers, not for installing system RAM modules in a desktop. ECC (Error-Correcting Code) memory is used mainly in servers/workstations where data integrity is critical and requires motherboard/CPU support; it is not the most likely choice for a typical desktop upgrade. Registered (buffered) memory is also primarily for servers and compatible platforms, improving stability with large memory configurations but not common in standard desktops. Therefore, the best answer for typical desktop RAM installation is DIMM.

• Question 479:

  An IT specialist is setting up a new, custom computer. The specialist wants to minimize the number of power cables to keep the internal components organized and uncluttered.

  Which of the following power supply types should the specialist use?

  A. Modular
  B. Redundant
  C. Linear
  D. External
  A. Modular

  ---

  Explanation

  A modular power supply allows the user to connect only the cables needed, reducing clutter and improving organization inside the case.

  From CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 -Power supplies:

  "Modular power supplies provide detachable cables, allowing users to use only the required connections for a neater build."

  Which of the following service models is the most suitable?

  A. Infrastructure as a Service
  B. Security as a Service
  C. Platform as a Service
  D. Software as a Service
  A. Infrastructure as a Service

  ---

  Explanation

  Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet such as servers, storage, and networking. It allows a business to quickly spin up virtual machines and is ideal for disaster recovery and scalable IT infrastructure needs.

  Option B:SecaaS focuses on cloud-delivered security, not infrastructure.

  Option C:PaaS offers development environments, not full virtual infrastructure.

  Option D:SaaS delivers applications over the internet (e.g., email, CRM) - not for disaster recovery.
